Abstract

L'invention concerne un dispositif d'entraînement d'une pluralité de moteurs, comprenant un onduleur connecté à une borne CC ; un moteur polyphasé connecté à l'onduleur ; et un moteur monophasé connecté en série au moteur polyphasé, le nombre de fréquences du courant entré dans le moteur polyphasé lors de l'entraînement du moteur monophasé et du moteur polyphasé à la même vitesse étant inférieur au nombre de fréquences du courant entré dans le moteur polyphasé lors de l'entraînement du moteur monophasé et du moteur polyphasé à des vitesses différentes. En conséquence, une pluralité de moteurs peuvent être entraînés simultanément à des vitesses différentes, à l'aide d'un seul onduleur.
